According to the press release, "Phase 1 of the project includes four station reconstructions (Lawrence, Argyle, Berwyn and Bryn Mawr), reconstruction of track structure and viaducts (including some that are more than 100 years old), and the construction of a rail bypass north of Belmont station to increase rail capacity and alleviate train congestion."

The press release also says, "The CTA intends to move forward with its promise to encourage redevelopment in the Red and Purple corridor as part of Phase 1. The CTA will seek a consultant in 2016 to work with local communities and elected officials to develop a Transit Oriented Development Plan for parcels located in the Lawrence-Bryn Mawr and Red-Purple Bypass project areas."
